ADJUSTABLE WIRE-TWISTING WRENCH.

Application filed June 2'7, 1887. Serial No. 242.654.

To all whom. it may concern.-

Be it known that I, CHARLES E. WIN'rRoDE, of Huntington, in the county of Huntington and State of Indiana, have invented certain new and useful Improvements in Adjustable Tire-Twisting renches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Hy invention relates to an improvement in adjustable wire-twisting wrenches; and. it consists in the combination of the casting of which the arms form a part, the pivoted adjustable part which is placed upon this casting and which has a jaw to correspond to each one of the arms of the casting, and an adjusting device for turning this adjustable part upon the casting, as will be more fully described hereinafter.

The object of my invention is to provide an adjustable wrench for twisting the wires for picket-fences, in which the parts are made adjustable in relation to each other, so that wires of different thicknesses can be twisted with the same facility.

Figure l is a plan view of a wrench embodying my invention. Fig. 2 is a vertical cross-section of the same. Fig. 3 is a perspective of the casting with the adjustable part removed. Fig. 4 is a perspective of the adjustable part by itself.

A represents the casting, which has the arms 13 made as a part thereof. The central portion of the casting is recessed, as shown, so as to form both a socket and a flat surface to receive the adjustable jaws or part which is to be placed thereon. Only three arms are here shown, but there may be a greater number if so preferred. These arms radiate in such a manner that two of them are always upon the side of the fence upon which the person is operating, thus enabling him to keep up a constant twisting motion. Formed upon one edge of one of the arms is a projection, 0, through which the adjusting set-screw D is passed for the purpose of adjusting the rotating casting F, which is pivoted upon the casting A, as

shown. This casting F is recessed upon its inner side, as shown in Fig. 4, so as to fit down into and over the recess, which is formed in one of the faces of the casting A, and turns upon the pivot G. This casting F has three arms or projections, H, which extend outward parallel or nearly parallel with the edges of the arms B, and which form one half of the jaws, between which the wires are caught to be twisted. The arm 13 forms one half of each jaw, and the projection H of the casting F forms the other. By the setscrew D, which bears against a shoulder, I, formed upon the casting F, the casting can be made to partially turn upon its pivot so as to either increase or decrease the size of all of the jaws at once. The farther the edges of the casting F are moved forward toward the edges of the arm the less the space is in which the wires are to be caught, and the wrench is adapted to be used upon wires of the smallest size. In proportion as the set-screw D is moved backward and the space is increased between the arms and the projections upon the castings F so larger wires can be introduced.

Heretofore the wrenches made for twisting wires have been made without any adjustable parts, and hence whenever the wrench became worn at any point the wrench became practically useless, and nothing further could be done with it until it had been dressed or repaired. By having one of the parts made adjustable, as here shown, the wires of the jaws can be increased and decreased at will, and thus adapted for wires of any size.

The pivot G, upon which the casting F turns, will preferably consist of a set-scre\v, which, after the set-screw D has been tightened in position, will also be tightened up, so as to assist in holding the adjustable casting F in position.

Having thus described my invention, I claim 1. The combination of a main casting pro vided with arms forming one half of thejaws, and an adjustable casting having projections corresponding with .the arms and forming the other half of the jaws, placed on the main casting, and means for holding the adjustable casting in any desired position, whereby the jaws areadapted for twisting wires of differcastingFin any desired position, substantially ent thicknesses, substantially as set forth. as described.
